This invention refers to an improved mort'ar material or composition; and it consistsin a mixture of ingredients substantially in the i proportions to be hereinafter described and claimed.

In making my improved mortar I use Francestown soapstone,which is quarried at Francestown, New Hampshire, and which differs 2o chemically from the ordinary soapstone or tale in that the latter contains'no oxide of aluminium, (Al,0,.) which is contained in Francestown soapstone to the extent of ten per cent., and also talc has fifteen per cent.

' more silica (Si'OQ than Francestowu soapstonc,which contains forty-five per cent. of silica. To five parts of pulverized Francestown soa )slone I add one part of cement and the two ingredients are thorougli|y commingled. To one part of this mixture I next add one part of sharp fine sand and one part of slaked lime. After the ingredients are thus mixed Elie mortar is ready to apply and is complete with the exception of the coloring The mortar thus composed is deing material to produce a colored mortar. This coloring is added to the compound inany proportion desired just before the .rnixiug.

Any colors may be used that are desired-- consisting of egmgnt, sand, slaked lime, anda sea 3 EOUtiilDlllg en p'er cen xlde of a uminium and some forty-five per cent. 0 silica. substantially as described.
